Based on the material content, waste is grouped into two types, namely organic waste (waste derived from animal, plant and human parts) and inorganic waste (waste derived from materials such as metal, glass, styrofoam, plastic and rubber). Inorganic waste is one of the coastal pollution problems, yet information about inorganic waste in mangrove ecosystem was relatively low, especially at Lesah Village, Tagulandang Sub district, Sitaro Regency. This study aims to determine the distribution of inorganic waste by type and to analyze the characteristic of inorganic waste based on the amount of size and weight found. The method used in this research is the line transects method at 3 different stations. The results showed that the types of marine debris that found were plastic, rubber, metal, and glass waste and there were 2 characteristics, namely mega-debris and macro-debris. Of the various types of debris obtained, plastic is the most commonly found, 161 items/23.329m2 (69.099 Items/ha) with a total weight of 1357.75 gram/ha and a total size of 1938.93 cm/ha. Followed by rubber debris as many as 5 items/23.329m2 (2.146 items/ha) with a total weight of 159.309 gram/ha and a total size of 59.871 cm/ha. Then, glass debris as many as 4 items/23.329m2 (1.717 items/ha) with a total weight of 402,159 grams/ha a total size of 31.030 cm/ha. Whereas, metal debris is the lowest value found as many as 3 item/23.329m2 (1.288 items/ha) with a total weight of 67.622 gram/ha and a total size of 19.528 cm/ha.Keywords: Inorganic waste, Mangrove Ecosystem, Desa Lesah
根据物质含量，废物分为两类，即有机废物(来自动物、植物和人体部位的废物)和无机废物(来自金属、玻璃、聚苯乙烯泡沫、塑料和橡胶等材料的废物)。无机废弃物是沿海污染问题之一，但红树林生态系统中无机废弃物的信息相对较少，特别是在西塔罗县塔古兰塘街道勒沙村。本研究旨在确定无机废物的类型分布，并根据所发现的无机废物的大小和重量来分析其特征。本研究使用的方法是3个不同站点的线样线法。结果表明，发现的海洋垃圾类型主要为塑料、橡胶、金属和玻璃废弃物，并具有大型垃圾和大型垃圾的2个特征。在收集到的各种垃圾中，最常见的是塑料，每23.329平方米(69.099件/公顷)有161件，总重量为1357.75克/公顷，总尺寸为1938.93厘米/公顷。其次是橡胶碎屑，5个/23.329m2(2.146个/ha)，总重量159.309 g /ha，总尺寸59.871 cm/ha。然后，玻璃碎片多达4件/23.329m2(1.717件/ha)，总重量为402159克/ha，总尺寸为31.030厘米/ha。其中金属碎屑含量最低，仅为3个/23.329m2(1.288个/ha)，总重量为67.622 g /ha，总尺寸为19.528 cm/ha。关键词:无机废弃物，红树林生态系统，德萨勒沙

Glutathion is a tripeptides produced by almost all living creatures, including marine fauna such as rotifers and shrimps. Judging from the important molecular role of glutathion in living cell, the ability of glutathion as antiviral compound, has been assed by application of the AutodockTools to predict the ability of glutathion as ligand to bind receptors of several viral diseases such as covid-19, malaria, and hepatitis B. Docking results of glutathion toward target receptor were shown by the parameter, Gibbs energy value, and supported by other data such as the amount of hidrogen bond, amino acid residues, and bond distance. Evidently, the glutathion could bind to each receptor of covid-19, malaria and hepatitis B, with values of Gibbs energy (∆G), -7,9, 7,1 and -7,1 kcal/mol, respectively. This proves that glutathion has ability to bind covid-19 receptor, even stronger than its ability to bind receptors of other viral diseases, and to the remdesevir. Between glutathion and covid-19 receptor, there were 11 hidrogen bonds, with distance ranged from 2,76 to 3,25 Å. These were stronger than those between glutathion and receptors of malaria and hepatitis B, only 8 and 4 Å hidrogen bonds, respectively. To develop glutathion as antiviral drug, it is necessary to carry out in vitro and in vivo analyses, prior to clinical test. Therefore, it requires to explore the marine fauna species that produce glutathion and their cultivation.Keywords: molecular docking, glutathion, marine fauna, autodock vina, viral diseases, binding affinity

Beach formation has an important role in protecting land from the action of the sea and it is useful for recreation, conservation and other uses. In “Wisata Bahari Sario” Kota Manado coastal area there is still a particular area of beach that is used for various purposes, so it is important to study its morphology. This research was conducted with the aim of describing morphology and analyzing oceanographic factors that affected the dynamic process of beach morphology. The results showed that the beach had an area of 422.69 m2, with the criteria for short slopes in the Northeast and long slopes in the Southwest. The shapes of the beach surface were in the form of gutters and shoots, their appearance was more visible towards the Southwest. In general, the deposition process took place more intensively in the Southwestern part of the beach. Keywords: Beach, Morphology, Slope, Deposition

The waters surrounding the Minahasa Peninsula are important areas of various activities by use of coastal and marine space. This research aims, firstly to describe direction, period and height of waves at several water areas around the Minahasa Peninsula in various season. Secondly to analyze the characteristic of daily and seasonal waves. The wave parameter, which reanalysis by ECMWF for 5 years (September 2014 to august 2019) were used in this research. By the analysis spasial-temporal, the results are presented by the rose grapich waves direction and stock chart. The wave propagation in the north season and transition season I, is dominated by the northeasterly wave. While the wave propagation in the southern season and the transitional season II, is more diverse directions. The characteristics of the waves formed in the southeast Minahasa waters in the north season and transitional season I, show that the wave period is greater than in the waters of Manado Bay and Bitung waters. Furthermore, the wave characteristics formed in the waters of the Minahasa Peninsula show a significant wave height in Bitung waters which is higher than the waters of Manado Bay and Southeast Minahasa waters.Keywords: Waves, ECMWF, Minahasa Peninsula Waters Perairan sekitar Semenanjung Minahasa merupakan kawasan penting dalam berbagai aktivitas pemanfaatan ruang pantai dan laut.

Hard coral is one of the main components of this forming coral reef ecosystem. Bulutui waters have coral reef ecosystems that have a direct role as a source of livelihood for people around these waters. However, there are non-environmentally friendly human activities such as fishing using explosives or chemical solutions that cause coral reef damage. The aimed of this research was to find out the condition of hard coral’s percentage cover and to described the frequency of hard coral’s occurance therefore it’s could be representative data at this location. Coral data was collected by using PIT (Point Intercept Transect) method. The value of percentage cover of hard corals at Bulutui waters are 20.58% and the value is categorized damaged. The total frequency of hard coral’s occurance at station 1 are 66 and dominated by Coral Submassive (CS), at station 2 are 23 and dominated by Coral Massive (CM), at station 3 are 18 and dominated by Coral Foliose (CF) and then at station 4 are 140 and dominated by Coral Foliose (CF).Keywords: Percentage Cover, Scleractinia Coral, Bulutui Waters, PIT Methods.
